Snorre B Hydrodynamics

Production Ship Main Strength and Fatigue Analysis

An unusual hull shape also involving three large moonpools was analysed wrt. structural strength and fatigue life of the main hull girder. The hull hydrodynamic model was assembled by the programs MTC-ShipLines and MTC-ShipMesh. The hydrodynamic analysis was run by WAMIT. To find the static and dynamic hull shear forces and bending moments for sections along the hull girder the program MTC-ShipLoads was run. Transfer functions of longitudinal stresses for a number of coordinates was also found by MTC-ShipLoads and extreme statistical values obtained for several sea states and heading. Based on the stress transfer functions the fatigue life of each coordinate was found using MTC-LongLife.
